Field Capacity of Water Solution

Follow our step by step solution on how to calculate Field Capacity of Water?

FIRST Step Consider the formula

F = \frac{Γ w \cdot d w}{Γ d}

Next Step Substitute values of Variables

∴

F = \frac{9.807kN/m³ \cdot 0.3m}{13.73kN/m³}

Next Step Convert Units

∴

F = \frac{9807N/m³ \cdot 0.3m}{13730N/m³}

Next Step Prepare to Evaluate

∴

F = \frac{9807 \cdot 0.3}{13730}

Next Step Evaluate

∴

F = 0.214282592862345

LAST Step Rounding Answer

∴

F = 0.2143
